The FWDM system employs a multiplexer at the transmitter to combine multiple wavelengths (each carrying signals up to 10G bit-rate) and a demultiplexer at the receiver to separate them. With low insertion loss, minimal polarization dependence, and high isolation, this filter ensures reliable performance in demanding applications.
Custom configurations available with various package types (Steel, ABS Box), connector options (LC, SC, FC, UPC, APC), fiber types, and wavelength combinations to meet specific application requirements.
